[0078] like Figure 1 As shown, the automated production line for flat wire motor rotors of the present invention includes, in sequence, an automated rotor core stacking device 100, a rotor shaft assembly device 300, a motor rotor flipping and transfer device 400, a cooling device, a rotor iron ring hot pressing device 600, and a laser marking device. The automated rotor core stacking device 100 is used to stack the annular end cap and the annular core; the rotor shaft assembly device 300 is used to heat the annular core and hot-press the rotor shaft into the annular core; the motor rotor flipping and transfer device 400 is used to flip the rotor shaft; the cooling device is used to cool the rotor; the rotor iron ring hot pressing device 600 is used to hot-press the iron ring into the rotor; and the laser marking device is used to mark the rotor. The automated production line for flat wire motor rotors of the present invention, by sequentially connecting the automated rotor core stacking device and other devices, forms a continuous production line, enabling automated assembly of flat wire motor rotors.

[0079] Specifically, the main features of the equipment required for the first production process in the automated production line of the flat wire motor rotor—the automated core stacking device 100—are as follows:

[0080] The automated iron core stacking device 100 is used to automatically stack the manually fed annular iron core and annular end cap, and transfer the stacked annular iron core and annular end cap to the rotor shaft assembly device 300, which is required for the second production process in the automated production line of flat wire motor rotors. The main structure and working steps of the automated iron core stacking device 100 are as follows:

[0081] like Figures 2-4As shown, the automated rotor core stacking device 100 includes an annular core feeding mechanism 101, an annular end cap feeding mechanism 102, a core stacking platform mechanism 103, and a first annular core transfer assembly 104a and a second annular core transfer assembly 104b that travel between the annular core feeding mechanism 101 and the core stacking platform mechanism 103. The first annular core transfer assembly 104a and the second annular core transfer assembly 104b are arranged in parallel, and both the first annular core transfer assembly 104a and the second annular core transfer assembly 104b adopt a slide rail platform structure. A core manipulator assembly 105a is provided on one side of the annular core feeding mechanism 101. The core manipulator assembly 105a is used to transfer the annular core located in the annular core feeding mechanism 101 to the first annular core transfer assembly 104a or the second annular core transfer assembly 104b. A core end cap robot assembly 105b is provided on one side of the core stacking platform mechanism 103. The core end cap robot assembly 105b is used to transfer the annular end cap located in the annular end cap feeding mechanism 102 to the core stacking platform mechanism 103. The core end cap robot assembly 105b is also used to transfer the annular core located in the first annular core transfer assembly 104a or the second annular core transfer assembly 104b to the core stacking platform mechanism 103. The first annular core transfer assembly 104a and the second annular core transfer assembly 104b alternately move back and forth between the annular core feeding mechanism 101 and the core stacking platform mechanism 103. Furthermore, the flat wire motor rotor core automated stacking device of the present invention includes a core imaging mechanism 106, which can be a CCD camera. The core robotic arm assembly 105a transfers the annular core to the core imaging mechanism 106 for imaging, and then transfers it to the first annular core transfer assembly 104a or the second annular core transfer assembly 104b.

[0082] In the operation of the automated stacking device for flat wire motor rotor cores of the present invention, the core robotic arm assembly 105a picks up a ring-shaped core from the ring-shaped core feeding mechanism 101 and places it in the core imaging mechanism 106 to take a picture and check for defects. After the ring-shaped core is found to be defective, it is placed on the first ring-shaped core transfer assembly 104a near the ring-shaped core feeding mechanism 101. The first ring-shaped core transfer assembly 104a carries the ring-shaped core from the side near the ring-shaped core feeding mechanism 101 to the side near the core stacking platform mechanism 103. Simultaneously, during the movement of the first ring-shaped core transfer assembly 104a, the core robotic arm assembly 105a picks up a ring-shaped core from the ring-shaped core feeding mechanism 101, and after the core imaging mechanism 106 completes the picture, it places the ring-shaped core on the second ring-shaped core transfer assembly 104b. When the first annular iron core transfer assembly 104a moves to the side near the iron core stacking platform mechanism 103, the iron core end cap robot assembly 105b first grabs the first annular end cap from the annular end cap feeding mechanism 102 and places it on the iron core stacking platform mechanism 103, and then grabs the annular iron core from the first annular iron core transfer assembly 104a and places it on the first annular end cap. After the placement of the annular iron core is completed, the first annular iron core transfer assembly 104a returns to the side near the annular iron core feeding mechanism 101; at the same time, the second annular iron core transfer assembly 104b carries the annular iron core from the side near the annular iron core feeding mechanism 101 to the side near the iron core stacking platform mechanism 103. The iron core end cap robot assembly 105b transfers the annular iron core located in the second annular iron core transfer assembly 104b to the iron core stacking platform mechanism 103. Specifically, the annular iron core in the second annular iron core transfer assembly 104b is stacked on the previous annular iron core. Similarly, the first annular core transfer assembly 104a and the second annular core transfer assembly 104b alternate back and forth until several annular cores required for rotor production are stacked on the first annular end cap. Then, the core end cap robotic arm assembly 105b picks up the second annular end cap from the annular end cap feeding mechanism 102 and places it onto the annular core, completing the stacking of the annular end cap and the annular core. From top to bottom, the sequence is: second annular end cap, several annular cores, and first annular end cap. This invention, by setting the first and second annular core transfer assemblies to alternate back and forth between the annular core feeding mechanism and the core stacking platform mechanism, effectively improves the stacking efficiency of the annular cores and annular end caps while achieving automated stacking.

[0083] In this embodiment, as Figure 5 and Figure 6As shown, the rotor core clamping fixture can be placed on the core stacking platform mechanism 103. Specifically, the core clamping fixture is placed on the core stacking platform mechanism 103 by manually holding the clamping fixture handle 208 located on the core clamping fixture. The core clamping fixture includes a core fixture base plate 201, a core clamping platform 202 disposed on the core fixture base plate 201 for placing the annular core and annular end cap, and a core clamping arm mechanism 203 disposed on the core fixture base plate 201. The core end cap manipulator assembly 105b can transport the annular core located on the first annular core transfer assembly 104a or the second annular core transfer assembly 104b to the core clamping platform 202. The core end cap robotic arm assembly 105b can also transport the annular end cap located in the annular end cap feeding mechanism 102 to the core clamping platform 202. The core clamping arm mechanism 203 includes a core clamping arm and a core clamping cylinder 203c that drives the core clamping arm to move toward or away from the core clamping platform 202. The core clamping cylinder 203c is fixed on the core tooling base plate 201. The output end of the core clamping cylinder 203c is connected to a core clamping arm rotation motor 203b. The output end of the core clamping arm rotation motor 203b is connected to the core clamping arm. The core clamping arm is L-shaped. Specifically, the core clamping arm includes a core pressing arm 203aa and a core clamping connecting arm 203ab. The output end of the core clamping arm rotation motor 203b is specifically connected to the core clamping connecting arm 203ab. The air passage through which the iron core clamping cylinder 203c drives the iron core clamping arm is connected to a locking valve that closes the air passage. The iron core tooling base plate 201 is provided with a pneumatic-electric connection plate 204, which is equipped with a pneumatic-electric connector. The air passage of the iron core clamping cylinder 203c is pneumatically connected to the pneumatic-electric connector, and the iron core clamping arm rotation motor 203b is electrically connected to the pneumatic-electric connector. A gas supply device that can be connected to the pneumatic-electric connector is also provided; in this embodiment, the gas supply device is a power supply and gas supply mechanism 107.

[0084] Before the core end cap robotic arm assembly 105b places the annular core and annular end cap onto the core clamping platform 202, the power supply and air supply mechanism 107 is connected to the pneumatic connector, the core clamping arm rotating motor 203b is energized, and the core clamping cylinder 203c is ventilated. The core clamping arm rotating motor 203b drives the core pressing arm 203aa to rotate, facilitating the placement of the annular core and annular end cap. After the annular core and annular end cap are placed on the core clamping platform 202, the core clamping arm rotating motor 203b drives the core pressing arm 203aa to rotate above the second annular end cap, and the core clamping cylinder 203c drives the core pressing arm 203aa to press the annular core and annular end cap firmly onto the core clamping platform 202. Subsequently, the power and air supply mechanism 107 is disconnected from the pneumatic connector. Since the air path driving the iron core clamping arm movement via the iron core clamping cylinder 203c is connected to a locking valve that closes the air path, even after the power and air supply mechanism 107 is disconnected, the iron core clamping arm, including the iron core pressing arm 203aa, can still clamp the annular iron core and annular end cap. The iron core clamping fixture can carry the annular iron core and annular end cap freely to the next production process device without being affected by the air path circuit connections. This invention, by connecting a locking valve that closes the air path in the air path driving the iron core clamping arm movement via the iron core clamping cylinder, facilitates the transfer of the annular iron core and annular end cap after the stacking of the annular iron core and annular end cap.

[0085] like Figures 5-7As shown, in this embodiment, the core stacking platform mechanism 103 includes a core stacking platform slide rail 103a, a core stacking platform 103b located on the core stacking platform slide rail 103a, and a core stacking platform driving assembly 103c that drives the core stacking platform 103b to slide on the core stacking platform slide rail 103a. Specifically, before the flat wire motor rotor core automated stacking device of the present invention operates, the core clamping fixture is placed onto the core stacking platform 103b by manually holding the clamping fixture handle 208 located on the core clamping fixture. One end of the iron core stacking platform slide rail 103a is close to the first annular iron core transfer assembly 104a and the second annular iron core transfer assembly 104b. The other end of the iron core stacking platform slide rail 103a is provided with a stacking and transfer mechanism 108. Specifically, the iron core stacking platform 103b can be moved to a side close to the first annular iron core transfer assembly 104a or close to the second annular iron core transfer assembly 104b, or the iron core stacking platform 103b can be moved into the stacking and transfer mechanism 108. The stacking and transfer mechanism 108 is provided with a stacking and transfer robot 108a for transferring the iron core clamping fixture from the iron core stacking platform 103b to the rotor shaft assembly device 300. The stacking and transfer robot 108a can be a three-axis robot. The iron core fixture base plate 201 is provided with a second fixture positioning and transfer block 207 for the stacking and transfer robot 108a to grasp. During the stacking process of the annular iron core and the annular end cap, the iron core stacking platform 103b is located near the first annular iron core transfer assembly 104a or near the second annular iron core transfer assembly 104b. After the annular iron core and the annular end cap are stacked and the power supply and air supply mechanism 107 is disconnected from the pneumatic connector, the iron core stacking platform 103b transfers the iron core clamping fixture to the stacking and transfer mechanism 108. The stacking and transfer robot 108a grips the second fixture positioning and transfer block 207, thereby realizing the transfer of the iron core clamping fixture. This invention, by providing a stacking and transfer mechanism, facilitates the transfer of the annular iron core and the annular end cap located on the iron core clamping fixture.

[0086] like Figure 8 As shown, in this embodiment, the iron core stacking platform 103b is provided with a clamping fixture positioning pin 103d, and the iron core clamping fixture is provided with a clamping fixture positioning hole that cooperates with the clamping fixture positioning pin 103d. This invention, through the cooperation of the clamping fixture positioning pin and the clamping fixture positioning hole, enables the iron core clamping fixture to move smoothly along the iron core stacking platform.

[0087] like Figure 5 and Figure 6As shown, the automated stacking device for flat wire motor rotor cores of the present invention includes a retractable stacking dummy shaft assembly 109. Both the core tooling base plate 201 and the core clamping platform 202 are provided with core tooling through holes, and the core stacking platform 103b is provided with a core platform through hole. The stacking dummy shaft assembly 109 can pass through both the core tooling through hole and the core platform through hole. During the stacking of the annular core and the annular end cap, the stacking dummy shaft assembly 109 extends and passes through the core tooling through hole and the core platform through hole, and the annular end cap and the annular core are fitted onto the dummy shaft. After the stacking of the annular core and the annular end cap is completed, the stacking dummy shaft assembly 109 retracts. The present invention, through the setting of the stacking dummy shaft assembly, helps to ensure the coaxiality of the annular core and the annular end cap during the stacking process.

[0088] like Figure 9 As shown, in this embodiment, the core end cap robotic arm assembly 105b includes a core end cap gripping module. The core end cap gripping module includes a retractable gripping ejection shaft 105ba and a gripping ejection block 105bb that cooperates with the gripping ejection shaft 105ba. The extension and retraction of the gripping ejection shaft 105ba causes the gripping ejection block 105bb to move along the radial direction of the gripping ejection shaft 105ba. The gripping ejection block 105bb is provided with an ejection return spring 105bc. When the core end cap robotic arm assembly 105b grips the annular core, the core end cap gripping module extends into the inner ring of the annular core, the gripping ejector shaft 105ba extends and drives the gripping ejector block 105bb to eject, and the gripping ejector block 105bb contacts the inner ring of the annular core to clamp the annular core; when it is necessary to place the annular core, the gripping ejector shaft 105ba retracts, and under the action of the ejection return spring 105bc, the gripping ejector block 105bb returns to its original position.

[0089] like Figure 10 and Figure 11As shown, the annular iron core feeding mechanism 101 includes an annular iron core feeding turntable 101a and a feeding turntable driving assembly 101b for driving the annular iron core feeding turntable 101a to rotate. An iron core feeding lifting assembly is located below the annular iron core feeding turntable 101b. The annular iron core feeding turntable 101a has a feeding turntable through hole, and the iron core feeding lifting assembly includes an annular iron core lifting rod 101c that is retractable and passes through the feeding turntable through hole. In this embodiment, the annular iron core feeding mechanism 101 is disc-shaped, with annular iron core feeding positions arranged around the disc. Each annular iron core feeding position has a feeding turntable through hole. In this embodiment, there are a total of 18 iron core feeding positions, arranged in groups of three. The iron core feeding lifting assembly includes a slide rail driving device for driving the annular iron core lifting rod 101c to move. The annular core lifting rod 101c is moved to different annular core loading positions by a sliding rail drive device, thereby lifting the annular cores at these different loading positions. This invention facilitates the loading of annular cores through the arrangement of the annular core loading turntable.

[0090] The main working steps of the automated iron core stacking device 100 are as follows:

[0091] S1a, the annular iron core feeding turntable 101a rotates, the annular iron core feeding mechanism 101 is manually fed, the annular end cap feeding mechanism 102 is manually fed, and the iron core clamping fixture is manually placed on the iron core stacking platform 103b.

[0092] S1b, the iron core robot arm assembly 105a grabs the annular iron core in the annular iron core feeding mechanism 101 and takes a picture of it in the iron core shooting mechanism 106. After confirming that the picture is correct, the annular iron core is grabbed onto the first annular iron core transfer assembly 104a located on one side of the annular iron core feeding mechanism 101.

[0093] S1c, the iron core stacking platform 103b is located near the first annular iron core transfer assembly 104a, and the first annular iron core transfer assembly 104a carries the annular iron core to the side near the iron core stacking platform 103b; at the same time, the iron core robot arm assembly 105a grabs the annular iron core in the annular iron core feeding mechanism 101 and takes it to the iron core shooting mechanism 106 for taking a picture. After confirming that the picture is correct, the annular iron core is grabbed onto the second annular iron core transfer assembly 104b located on the side of the annular iron core feeding mechanism 101;

[0094] S1d, the power supply and air supply mechanism 107 is connected to the pneumatic connector, the stacked dummy shaft assembly 109 extends out, the iron core end cap robot assembly 105b grabs the first annular end cap from the annular end cap feeding mechanism 102 and places it on the iron core clamping platform 202, the stacked dummy shaft assembly 109 passes through the first annular end cap; then, the iron core end cap robot assembly 105b grabs the annular iron core from the first annular iron core transfer assembly 104a and places it on the first annular end cap at a specific position, the stacked dummy shaft assembly 109 passes through the annular iron core.

[0095] S1e, the second annular iron core transfer assembly 104b carries the annular iron core to the side near the iron core stacking platform 103b, while at the same time, the first annular iron core transfer assembly 104a returns to the side near the annular iron core feeding mechanism 101.

[0096] S1f, the core end cap robot assembly 105b picks up the annular core from the second annular core transfer assembly 104b and places it on the previous annular core at a specific position; the stacked dummy shaft assembly 109 passes through the two annular cores; at the same time, the core robot assembly 105a picks up the annular core from the annular core feeding mechanism 101, takes a picture, and places it on the first annular core transfer assembly 104a;

[0097] S1g, the first annular iron core transfer assembly 104a moves to the side near the iron core stacking platform 103b, and the second annular iron core transfer assembly 104b returns to the side near the annular iron core feeding mechanism 101; and so on, until several annular iron cores required for production are stacked on the iron core clamping platform 202, the iron core end cap robot assembly 105b grabs the second annular end cap from the annular end cap feeding mechanism 102 and places it onto several annular iron cores, and the stacking dummy shaft assembly 109 passes through the first annular end cap, several annular iron cores, and the second annular end cap from bottom to top;

[0098] S1h, the iron core clamping arm rotating motor 203b drives the iron core pressing arm 203aa to rotate above the second annular end cover, and the iron core clamping cylinder 203c drives the iron core pressing arm 203aa to press the first annular end cover, several annular iron cores, and the second annular end cover onto the iron core clamping platform 202.

[0099] S1i, the stacked dummy shaft assembly 109 retracts, the power supply and air supply mechanism 107 is disconnected from the pneumatic connector, and the first annular end cap, several annular iron cores, and the second annular end cap are kept in a pressed state under the action of the locking valve.

[0100] S1j, the iron core stacking platform 103b moves into the stacking and transplanting mechanism 108;

[0101] S1k, the stacking and transplanting robot 108a grasps the second tooling positioning and transfer block 207 located on the iron core clamping tooling, thereby realizing the grasping of the first annular end cap, several annular iron cores, and the second annular end cap;

[0102] S1l, under the action of the stacking and transplanting robot 108a, the iron core clamping fixture carries the first annular end cap, several annular iron cores, and the second annular end cap to the device required for the second production process in the flat wire motor rotor automated production line—the rotor shaft assembly device 300.

[0103] Specifically, the main features of the rotor shaft assembly device 300, the equipment required for the second production process in the automated production line for flat wire motor rotors, are as follows:

[0104] The rotor shaft assembly device 300 is used to receive the manually fed rotor shaft and heat-press the rotor shaft into the annular iron core. After the rotor shaft is pressed into the iron core, the rotor is transferred to the third production process in the automated production line of the flat wire motor rotor—the motor rotor flipping and transfer device 400. The main structure and working steps of the rotor shaft assembly device 300 are as follows:

[0105] Figures 12-13 This is an overall structural diagram of the rotor shaft assembly device 300. Figure 14 This is a structural diagram of the rotor core clamping fixture that has completed core stacking and flows out of the rotor core automated stacking device 100. The rotor shaft assembly device 300 is also provided with a power supply and air supply mechanism 107 that can be connected to the pneumatic and electrical connector. Figures 15-17As shown, the rotor shaft assembly device 300 includes a core heating mechanism 301, a rotor shaft hot pressing mechanism 302, and a heated core transfer mechanism 303 that travels between the core heating mechanism 301 and the rotor shaft hot pressing mechanism 302. The core heating mechanism 301 includes a core heating coil assembly 301a, and the rotor shaft hot pressing mechanism 302 includes a rotor shaft hot pressing assembly 302a. The heated core transfer mechanism 303 includes a heated core transfer slide rail 303a arranged along the Y-axis, a heated core transfer platform 303b located on the heated core transfer slide rail 303a, and a heated core transfer drive device 303c that drives the heated core transfer platform 303b to move on the heated core transfer slide rail 303a. The heated core transfer platform 303b is provided with a heated core transfer connecting plate 303d arranged along the Z-axis. A left heated core clamping part 303e and a right heated core clamping part 303f are connected to the heating core transfer connecting plate 303d. The clamping arm of the left heated core clamping part 303e is arranged along the X-axis, and the left heated core clamping part 303e is located closer to the heated core mechanism 301. The right heated core clamping part 303f is located closer to the rotor shaft hot pressing mechanism 302. The right heating core clamping part 303f can rotate along a fixed axis. In this embodiment, the right heating core clamping part 303f rotates along the Z-axis under the action of a gear and rack mechanism. The left heating core clamping part 303e and the right heating core clamping part 303f can move closer to each other or further away from each other to clamp the annular core. In this embodiment, the right heating core clamping part 303f is configured as a structure that can only rotate and not move. The left heating core clamping part 303e can move along the Y-axis through a slide rail mechanism, that is, the left heating core clamping part 303e can move toward or away from the right heating core clamping part 303f.In the specific implementation process, the heated iron core transfer mechanism 303 moves into the iron core heating mechanism 301, and the right heated iron core clamping part 303f rotates to be parallel to the left heated iron core clamping part 303e; after the annular iron core is heated in the iron core heating mechanism 301, the left heated iron core clamping part 303e moves toward the right heated iron core clamping part 303f to clamp the heated annular iron core; then, under the action of the heated iron core transfer drive device 303c, the heated annular iron core moves to the rotor shaft hot pressing mechanism 30. After step 2, the left heating core clamping part 303e returns to its original position. Simultaneously, the right heating core clamping part 303f rotates to avoid the annular core located in the rotor shaft hot pressing mechanism 302, until the clamping arm of the right heating core clamping part 303f faces the Y-axis direction. The heating core transfer mechanism 303 then returns to the core heating mechanism 301. During the return process of the heating core transfer mechanism 303, the rotor shaft hot pressing mechanism 302 performs the process of hot pressing the rotor shaft to the annular core. The flat wire motor rotor shaft assembly device of the present invention sets the right heating core clamping part of the heating core transfer mechanism close to the rotor shaft hot pressing mechanism, sets the left heating core clamping part close to the core heating mechanism, and sets the right heating core clamping part to be rotatable along a fixed axis. When the heated iron core transfer mechanism returns from the rotor shaft hot pressing mechanism to the rotor shaft hot pressing mechanism, the right heated iron core clamping part rotates to avoid the iron core located in the rotor shaft hot pressing mechanism. Thus, there is no need to wait for the rotor shaft to be assembled before the heated iron core transfer mechanism returns to the rotor shaft hot pressing mechanism, which effectively improves the assembly efficiency of the iron core and the rotor shaft.

[0106] In this embodiment, as Figure 14 , Figure 18 , Figure 19 As shown, the right heating core clamping part 303f is provided with a first core positioning and transfer block 303g, and the left heating core clamping part 303e is provided with a second core positioning and transfer block 303h. The first core positioning and transfer block 303g and the second core positioning and transfer block 303h are arranged facing each other. Specifically, when the heating core transfer mechanism 303 needs to clamp the heated annular core, the first core positioning and transfer block 303g and the second core positioning and transfer block 303h cooperate with the first tooling positioning and transfer block 206 located on the core tooling base plate 201, so that the heating core transfer mechanism 303 can stably clamp the annular core located on the core tooling base plate 201. The present invention, through the setting of the first core positioning and transfer block and the second core positioning and transfer block, facilitates the heating core transfer mechanism to clamp and transfer the annular core more stably.

[0107] In this embodiment, as Figures 20-22As shown, under the action of the core heating coil driving device, the coil group of the core heating coil assembly 301a can move up and down along the height direction. Specifically, the core heating coil assembly 301a includes an inner core heating coil 301aa for heating the inner ring of the annular core and an outer core heating coil 301ab for heating the outer ring of the annular core. When heating the annular core, firstly, the core clamping arm mechanism 203 releases the pressure on the annular core, and the clamping arm of the core clamping arm mechanism 203 rotates and moves away, so that the core heating coil assembly 301a can cover the annular core. Immediately afterwards, the inner core heating coil 301aa extends downward into the inner ring of the annular core, and the outer core heating coil 301ab covers the outer ring of the annular core. The inner and outer rings of the annular core are heated together under the action of the core heating coil assembly 301a. This invention improves the heating effect of the annular iron core by setting up an inner iron core heating coil and an outer iron core heating coil.

[0108] In this embodiment, as Figures 23-24 As shown, a rotor shaft feeding mechanism 304 is also provided on one side of the rotor shaft hot pressing mechanism 302. The rotor shaft feeding mechanism 304 includes a rotor shaft gripping robot 304a, which may be a three-axis robot. The rotor shaft hot pressing mechanism 302 includes a rotor shaft receiving component 302b, which can move along the height direction. The rotor shaft receiving component 302b can reciprocate between the rotor shaft hot pressing component 302a and the rotor shaft feeding mechanism 304. The rotor shaft receiving component 302b can receive the rotor in the rotor shaft gripping robot 304a, and the rotor shaft receiving component 302b can move the rotor shaft to below the rotor shaft hot pressing component 302a.

[0109] Specifically, such as Figures 23-26As shown, the rotor shaft hot pressing mechanism 302 includes a rotor shaft hot pressing frame 302c, a rotor shaft hot pressing frame plate 302d on the rotor shaft hot pressing frame 302c, and a rotor shaft receiving assembly 302b including a rotor shaft receiving plate 302ba disposed below the rotor shaft hot pressing frame plate 302d and a rotor shaft receiving first driving assembly 302bb fixed on the rotor shaft hot pressing frame plate 302ba and driving the rotor shaft receiving plate 302ba to move along the height direction. The rotor shaft receiving first driving assembly 302bb can be a lead screw structure or a cylinder structure. The rotor shaft receiving plate 302ba is provided with a rotor shaft positioning groove 302bc. A rotor shaft receiving module for transferring the rotor shaft is provided between the rotor shaft receiving plate 302ba and the rotor shaft hot press frame plate 302d. A second drive assembly 302bd for receiving the rotor shaft is fixed on the rotor shaft receiving plate 302ba. The second drive assembly 302bd drives the rotor shaft receiving module to reciprocate between the rotor shaft hot press assembly 302a and the rotor shaft feeding mechanism 304. The rotor shaft receiving plate 302ba has a through slot for the rotor shaft to pass through. The rotor shaft receiving module for transferring the rotor shaft can be a clamping arm for holding the rotor shaft, or it can be a clamping plate with a clamping part. The second drive assembly 302bd can be a lead screw structure.

[0110] In this embodiment, a rotor shaft lifting mechanism 304b is also provided below the rotor shaft gripping robot 304a. When loading the rotor shaft, the rotor shaft is placed on the rotor shaft loading plate 304c, which is placed on the rotor shaft loading trolley 304d. The rotor shaft loading trolley 304d, containing the rotor shaft, is manually pushed into the rotor shaft loading mechanism 304. The rotor shaft lifting mechanism 304b can lift the rotor shaft loading plate 304c together with the rotor shaft, and the rotor shaft gripping robot 304a grips the rotor shaft. Simultaneously, the rotor shaft receiving module descends under the action of the first rotor shaft receiving drive component 302bb, and moves towards the rotor shaft loading mechanism 304 under the action of the second rotor shaft receiving drive component 302bd until it reaches the rotor shaft receiving position, at which point the rotor shaft receiving module stops moving. After the rotor shaft gripping robot 304a transfers the rotor shaft to above the rotor shaft receiving module, it is driven to descend and pass the rotor shaft through the rotor shaft through slot, simultaneously positioning the rotor shaft in the rotor shaft positioning slot 302bc. Then, the rotor shaft receiving module receives the rotor shaft, and the rotor shaft gripping robot 304a releases the rotor shaft. Subsequently, under the action of the first drive assembly 302bb and the second drive assembly 302bd, the position of the rotor shaft receiving module is adjusted until the rotor shaft is positioned below the pressure head of the rotor shaft hot pressing assembly 302a. This invention, through the rotor shaft feeding mechanism and the rotor shaft receiving assembly, facilitates the automatic feeding of rotor shafts.

[0111] like Figure 13 , Figure 17 and Figure 27As shown, the present invention includes a cold iron core transfer mechanism 305 for transporting a cold annular iron core to the iron core heating mechanism 301. The cold iron core transfer mechanism 305 includes a cold iron core transfer slide rail 305a, a cold iron core transfer platform 305b sliding on the cold iron core transfer slide rail 305a, and a cold iron core transfer drive assembly 305c for driving the movement of the cold iron core transfer platform 305b. The cold iron core transfer slide rail 305a is arranged along the X-axis direction. The heated iron core transfer mechanism 303 can remove the rotor iron core clamping fixture from the cold iron core transfer mechanism 305. It also includes a first hot-pressing transfer mechanism 306, and the cold iron core transfer mechanism 305 can travel back and forth between the first hot-pressing transfer mechanism 306 and the iron core heating mechanism 301. The first hot-pressing transfer mechanism 306 is equipped with a device required for transferring the cold annular iron core from the first production process in the flat wire motor rotor automated production line—the rotor iron core automated stacking device 100—to the cooling iron core transfer robot 306a on the cooling iron core transfer mechanism 305. The cooling iron core transfer robot 306a can be a three-axis robot. In the flat wire motor rotor assembly line, after the first annular end cap, the annular core, and the second annular end cap are stacked on the rotor core clamping fixture, the cooling core transfer robot 306a grabs the rotor core clamping fixture. Simultaneously, the cold core transfer platform 305b moves close to the first hot-pressing transfer mechanism 306, and the cooling core transfer robot 306a places the rotor core clamping fixture carrying the annular core onto the cold core transfer platform 305b. Then, the cooling core transfer mechanism 305 transports the rotor core clamping fixture carrying the annular core to the core heating mechanism 301. This invention, through the setting of the cold core transfer mechanism and the first hot-pressing transfer mechanism, realizes the automatic transport of the annular core to the core heating mechanism.

[0112] like Figure 15 As shown, the core heating mechanism 301 includes a core temperature measuring component 301b. A temperature measuring through-hole is provided on the cold core transfer platform 305b. The core temperature measuring component 301b is located below the core heating coil assembly 301a, and can extend and pass through the temperature measuring through-hole. When the cooling core transfer mechanism 305 transports the rotor core clamping fixture carrying the annular core to below the core heating coil assembly 301a, the core heating coil assembly 301a descends. Simultaneously, the core temperature measuring component 301b extends and passes through the temperature measuring through-hole to measure the temperature of the annular core. This invention, through the arrangement of the core temperature measuring component and the temperature measuring through-hole, facilitates the monitoring of the heating status of the annular core.

[0113] like Figure 13 , Figure 17 and Figure 28As shown, the present invention includes a hot-pressed rotor transfer mechanism 307 for transporting a rotor after hot-pressing the rotor shaft assembly away from the hot-pressing mechanism 302. The hot-pressed rotor transfer mechanism 307 includes a hot-pressed rotor transfer slide rail 307a, a hot-pressed rotor transfer platform 307b sliding on the hot-pressed rotor transfer slide rail 307a, and a hot-pressed rotor transfer drive assembly 307c for driving the hot-pressed rotor transfer platform 307b. The hot-pressed rotor transfer slide rail 307a is also arranged along the X-axis direction. The heated iron core transfer mechanism 303 can place a clamping fixture carrying an annular iron core onto the hot-pressed rotor transfer mechanism 307. It also includes a second hot-pressing transfer mechanism 308. The hot-pressing rotor transfer mechanism 307 can travel back and forth between the second hot-pressing transfer mechanism 308 and the rotor shaft hot-pressing mechanism 302. The second hot-pressing transfer mechanism 308 is equipped with a device for transferring the rotor, after the rotor shaft hot-pressing assembly is completed, from the hot-pressing rotor transfer mechanism 307 to the third production process in the flat wire motor rotor automated production line—the hot-pressing rotor transfer robot 308a in the motor rotor flipping transfer device 400. The cooling iron core transfer robot 308a can also be a three-axis robot. In the flat wire motor rotor assembly line, after the rotor shaft is hot-pressed into the annular iron core, the hot-pressing rotor transfer mechanism 307 carries the hot-pressed rotor from the rotor shaft hot-pressing mechanism 302 to the second hot-pressing transfer mechanism 308. The cooling iron core transfer robot 308a grabs the rotor and transfers it to the next device in the flat wire motor rotor production line. This invention achieves automatic rotation of the rotor after the hot pressing process is completed by setting up a hot pressing rotor transfer mechanism and a second hot pressing transfer mechanism.

[0114] like Figure 17 and Figure 24 As shown, the rotor shaft hot pressing mechanism 302 includes a hot pressing dummy shaft assembly 302e. The hot pressing rotor transfer platform 307b is provided with a hot pressing dummy shaft through hole. The hot pressing dummy shaft assembly 302e is located below the rotor shaft hot pressing assembly 302a, and can extend and pass through the hot pressing dummy shaft through hole. When the hot pressing rotor transfer mechanism 307b carries the heated annular iron core and is located below the rotor shaft hot pressing assembly 302a, and the rotor shaft is located between the heated annular iron core and the rotor shaft hot pressing assembly 302a, the rotor shaft hot pressing assembly 302a descends. Simultaneously, the hot pressing dummy shaft assembly 302e can extend and pass through the hot pressing dummy shaft through hole. This invention, through the setting of the hot pressing dummy shaft assembly and the hot pressing dummy shaft through hole, facilitates ensuring the coaxiality of the iron ring during rotor shaft hot pressing.

[0115] The main working steps of the rotor shaft assembly device 300 are as follows:

[0116] S2a, after the first annular end cap, the annular iron core, and the second annular end cap are stacked on the rotor iron core clamping fixture, the gas and power to the rotor iron core clamping fixture are cut off, the cold iron core transfer platform 305b moves to the first hot pressing transfer mechanism 306, and the cooling iron core transfer robot 306a grabs the rotor iron core clamping fixture onto the cold iron core transfer platform 305b.

[0117] S2b, under the drive of the cold iron core transfer drive assembly 305c, the cold iron core transfer platform 305b transports the rotor iron core clamping fixture to the iron core heating mechanism 301, specifically transporting the rotor iron core clamping fixture directly below the iron core heating coil assembly 301a.

[0118] S2c, the rotor core clamping fixture is ventilated and energized, the core clamping arm mechanism 203 releases the pressure on the annular core and other components, and rotates in a direction away from the annular core.

[0119] S2d, the iron core heating coil assembly 301a descends and heats the annular iron core; at the same time, the iron core temperature measuring assembly 301b rises and monitors the temperature of the annular iron core.

[0120] After the annular core heating is completed (S2e), the rotor core clamping fixture is energized and powered. After the core clamping arm mechanism 203 presses the annular core and other components again, the rotor core clamping fixture is de-energized and powered off. At the same time, the heated core transfer mechanism 303 is located in the core heating mechanism 301, and the clamping arm of the right heated core clamping part 303f rotates to face the Y-axis direction.

[0121] S2f, the left heating core clamping part 303e moves toward the right heating core clamping part 303f, clamps the rotor core clamping fixture, and transfers the rotor core clamping fixture to the rotor shaft hot pressing mechanism 302; at the same time, the hot pressing rotor transfer platform 307b is located in the rotor shaft hot pressing mechanism 302.

[0122] S2g, the clamping arm of the right heating core clamping part 303f rotates until it is turned toward the Y-axis direction, and the left heating core clamping part 303e moves away from the right heating core clamping part 303f, placing the rotor core clamping fixture carrying the annular core and other components onto the hot press rotor transfer platform 307b.

[0123] S2h, the cold iron core transfer platform 305b moves toward the first hot-pressing transfer mechanism 306, and the heated iron core transfer mechanism 303 moves toward the iron core heating mechanism 301; simultaneously, when the rotor shaft loading trolley 304d is pushed into the rotor shaft loading mechanism 304, the rotor shaft lifting mechanism 304b lifts the rotor shaft, the rotor shaft gripping robot 304a grips the rotor shaft and transports it toward the rotor shaft hot-pressing mechanism 302; the rotor shaft receiving module moves downward under the action of the rotor shaft receiving first driving component 302bb, and the rotor shaft receiving module moves toward the rotor shaft loading mechanism 304 under the rotor shaft receiving second driving component 302bd; finally, the rotor shaft gripping robot 304a transfers the rotor shaft into the rotor shaft receiving module.

[0124] S2i, the first drive assembly 302bb and the second drive assembly 302bd move the rotor shaft between the rotor shaft hot pressing assembly 302a and the annular iron core and other components; at the same time, the rotor iron core clamping fixture is ventilated and energized, and the iron core clamping arm mechanism 203 releases the clamping on the annular iron core and other components and rotates in a direction away from the annular iron core.

[0125] S21j, the rotor shaft hot pressing assembly 302a descends, and at the same time, the hot pressing dummy shaft assembly 302e extends, and the rotor shaft hot pressing assembly 302a presses the rotor shaft into components such as the annular iron core.

[0126] S21k, the hot-pressed rotor transfer platform 307b transports the rotor, after the rotor shaft and iron core have been assembled, to the second hot-pressed transfer mechanism 308.

[0127] S21l, the hot-pressed rotor transfer robot 308a grabs the rotor shaft and the iron core after they are assembled, and transfers it to the third production process in the next step of the flat wire motor rotor automated production line—the motor rotor flipping and transfer device 400.

[0128] Specifically, the main features of the equipment required for the third production process in the automated production line for flat wire motor rotors—the motor rotor flipping and transfer device 400—are as follows:

[0129] The motor rotor flipping and transfer device 400 is used to receive the rotor after the rotor shaft has been hot-pressed and assembled, and to flip the rotor 180 degrees after the rotor shaft has been pressed into the iron core. Specifically, it flips the rotor shaft, which is set along the height direction, 180 degrees. It is also used to transfer the rotor, after the flipped rotor shaft has been pressed into the iron core, to the cooling device required for the fourth production process in the automated production line of flat wire motor rotors. The main structure and working steps of the motor rotor flipping and transfer device 400 are as follows:

[0130] like Figures 29-31 As shown, the motor rotor flipping and transferring device 400 includes a flipping and transferring bracket 415, a first flipping and transferring base plate 416 movable along the X1 axis on the flipping and transferring bracket 415, a first flipping and transferring drive assembly for driving the first flipping and transferring base plate 416, a second flipping and transferring base plate 417 movable along the Y1 axis above the first flipping and transferring base plate 416, and a second flipping and transferring drive assembly fixed on the first flipping and transferring base plate 416 and driving the second flipping and transferring base plate 417. A clamping and flipping mechanism is provided below the first flipping and transferring base plate 416, and a third flipping and transferring drive assembly is provided on the second flipping and transferring base plate 417 for driving the clamping and flipping mechanism along the Z1 axis.

[0131] like Figures 32-34 As shown, the clamping and flipping mechanism includes a clamping and flipping plate 401, a left clamping and flipping part 402 and a right clamping and flipping part 403 that can move in opposite directions on the clamping and flipping plate 401, and a clamping cylinder component for driving the left clamping and flipping part 402 and the right clamping and flipping part 403 to move. Specifically, a clamping and flipping slide rail 404a is provided on one side of the clamping and flipping plate 401, and at least two clamping and flipping sliders 404b are provided on the clamping and flipping slide rail 404a, wherein at least one clamping and flipping slider 404b is connected to the left clamping and flipping part 402, and at least one clamping and flipping slider 404b is connected to the right clamping and flipping part 403. The clamping cylinder component is fixed on the clamping flip plate 401 and located between the left clamping flip part 402 and the right clamping flip part 403. The clamping cylinder component includes a left clamping cylinder 405a that drives the left clamping flip part 402 to move, and a right clamping cylinder 405b that drives the right clamping flip part 403 to move. A synchronizing block 406 that can rotate along a fixed axis is also fixed on the other side of the clamping flip plate 401. The synchronizing block 406 is provided with a first fixed end and a second fixed end. The first fixed end and the second fixed end are both located on the same straight line passing through the fixed axis, and the first fixed end and the second fixed end are respectively located on both sides of the fixed axis. The distance from the first fixed end and the second fixed end to the fixed axis is the same. The left clamping and flipping part 402 is connected to a first synchronous extension plate 407a that passes through the clamping and flipping plate 401, and the first synchronous extension plate 407a is connected to a first synchronous rod 408a that is connected to the first fixed end; the right clamping and flipping part 403 is connected to a second synchronous extension plate 407b that passes through the clamping and flipping plate 401, and the second synchronous extension plate 407b is connected to a second synchronous rod 408b that is connected to the second fixed end.

[0132] Since the left clamping and flipping part 402 is connected to the first fixed end located on the synchronization block 406, and the right clamping and flipping part 403 is connected to the second fixed end located on the synchronization block 406; and since the distances from the first fixed end and the second fixed end to the fixed shaft are the same, the rotation of the synchronization block 406 drives the left clamping and flipping part 402 and the right clamping and flipping part 403 to move synchronously. That is, it is possible that when the thrust of the left clamping cylinder 405a and the right clamping cylinder 405b is inconsistent, under the influence of the synchronization block 406, the clamping cylinder with the larger thrust can drive the clamping cylinder with the smaller thrust to move, that is, drive the left clamping and flipping part 402 and the right clamping and flipping part 403 to move synchronously. The clamping and flipping mechanism of the present invention, by providing a synchronization block that can rotate along a fixed shaft on the clamping and flipping plate, and by driving the left clamping and flipping part and the right clamping and flipping part to move synchronously through the rotation of the synchronization block, is beneficial for the clamping and flipping mechanism to achieve precise clamping of components, especially rotor shafts.

[0133] In this embodiment, as Figure 32 and Figure 33 As shown, to facilitate the clamping and flipping of the component, the left clamping and flipping part 402 is provided with a rotatably connected left clamping and flipping claw 409a, and the right clamping and flipping part 403 is provided with a rotatably connected right clamping and flipping claw 409b. The left clamping and flipping claw 409a and the right clamping and flipping claw 409b are arranged facing each other, and both the left clamping and flipping claw 409a and the right clamping and flipping claw 409b are provided with openings for clamping the rotor shaft. Both the left clamping and flipping claw 409a and the right clamping and flipping claw 409b are provided with clamping and flipping anti-slip pads 410. With the provision of anti-slip pads, the clamping and flipping mechanism of the present invention can more stably grip the rotor shaft when clamping the rotor shaft, especially when clamping the rotor shaft of a flat wire motor.

[0134] In an embodiment, such as Figure 32 and Figure 33As shown, the clamping and flipping mechanism of the present invention further includes a flipping motor assembly 411 for driving the left clamping and flipping claw 409a to rotate, and a flipping synchronization assembly connecting the left clamping and flipping claw 409a and the right clamping and flipping claw 409b and for driving the right clamping and flipping claw 409b to flip synchronously. Specifically, a first flipping rod is connected between the left clamping and flipping claw 409a and the output end of the flipping motor assembly 411. The flipping synchronization assembly includes a first flipping synchronization belt 412a connected to the first flipping rod, and a second flipping rod 413 connected to the right clamping and flipping claw 409b. A second flipping synchronization belt 412b is connected to the second flipping rod 413, and a flipping synchronization rod 414 is connected between the first flipping synchronization belt 412a and the second flipping synchronization belt 412b. When the flipping motor assembly 411 drives the left clamping flipping claw 409a to flip, the power is sequentially transmitted through the first flipping synchronous belt 412a, the flipping synchronous rod 414, and the second flipping synchronous belt 412b, ultimately driving the right clamping flipping claw 409b to flip synchronously with the left clamping flipping claw 409a. The synchronous flipping assembly ensures that the left and right clamping flipping claws flip synchronously, improving the stability of components, especially the rotor shaft, during the flipping process.

[0135] like Figures 29-31 As shown, when the motor rotor reversing and transferring device is in use, under the action of the first reversing and transferring drive assembly, the second reversing and transferring drive assembly, and the third reversing and transferring drive assembly, the clamping and reversing mechanism of the present invention is moved to the first position. The left clamping and reversing part and the right clamping and reversing part clamp the rotor shaft after it has been pressed into the iron core in the required device of the previous production process in the automated production line of the flat wire motor rotor, and reverse the rotor shaft by 180 degrees. Under the action of the first reversing and transferring drive assembly, the second reversing and transferring drive assembly, and the third reversing and transferring drive assembly, the rotor being assembled is transferred to the required device of the next production process in the automated production line of the flat wire motor rotor. The motor rotor reversing and transferring device of the present invention, by setting up the reversing and transferring drive assembly and the clamping and reversing mechanism, facilitates the reversing and transferring of rotors, especially rotors in the assembly of flat wire motors.

[0136] Specifically, such as Figures 29-31As shown, the third flip-transfer drive assembly includes a third flip-transfer motor 418 fixed above the second flip-transfer base plate 417. The output end of the third flip-transfer motor 418 is connected to a second flip-transfer screw 419 arranged along the height direction. The other end of the second flip-transfer screw 419 is connected to the clamping flip plate 401. Both the first flip-transfer base plate 416 and the second flip-transfer base plate 417 are provided with a first flip-transfer through hole for the second flip-transfer screw 419 to pass through. A flip-transfer connector 420, which cooperates with the second flip-transfer screw 419, is sleeved on the second flip-transfer screw 419. The flip-transfer connector 420 is fixed to the second flip-transfer base plate 417. The rotation of the third flip-transfer motor 418 drives the second flip-transfer screw 419 to rotate. Under the action of the flip-transfer connector 420, the second flip-transfer screw 419 moves along the height direction, thereby driving the clamping flip mechanism to move along the height direction.

[0137] At the same time, such as Figure 35 As shown, both the first flip-transfer base plate 416 and the second flip-transfer base plate 417 are provided with a second flip-transfer through hole. A flip-transfer guide shaft 421, arranged along the height direction, is provided in the second flip-transfer through hole. One end of the flip-transfer guide shaft 421 is connected to the clamping flip plate 401, and the other end is connected to a flip-transfer limiting plate 422 located above the second flip-transfer base plate 417. The flip-transfer limiting plate effectively prevents the clamping flip mechanism from falling due to the breakage of the second flip-transfer lead screw.

[0138] Specifically, such as Figure 34 and Figure 35 As shown, the first flipping and transferring drive assembly includes a first flipping and transferring motor 423 fixed on the first flipping and transferring base plate 416. A flipping and transferring gear 424 is connected to the output shaft of the first flipping and transferring motor 423. A flipping and transferring rack 425 is provided on the flipping and transferring bracket 415 along the X-axis direction, meshing with the flipping and transferring gear 424. Driven by the first flipping and transferring motor 423, the first flipping and transferring base plate 416 is driven to move along the X1-axis direction through the cooperation of the flipping and transferring gear 424 and the flipping and transferring rack 425, thereby driving the second flipping and transferring base plate 417 to move along the X1-axis direction, and further driving the clamping and flipping mechanism to move along the X1-axis direction.

[0139] Specifically, such as Figure 35As shown, the second flip-transfer drive assembly includes a second flip-transfer motor 426 fixed on the first flip-transfer base plate 416. The output end of the second flip-transfer motor 426 is connected to a first flip-transfer lead screw 427 arranged along the Y1 axis. A flip-transfer connecting plate 428 that cooperates with the first flip-transfer lead screw 427 is sleeved on the first flip-transfer lead screw 427. The flip-transfer connecting plate 428 is connected to the second flip-transfer base plate 417. The rotation of the second flip-transfer motor 426 drives the second flip-transfer motor 426 to rotate, thereby driving the flip-transfer connecting plate 428 to move along the Y1 axis, thereby driving the second flip-transfer base plate 417 to move along the Y1 axis, and further driving the clamping and flipping mechanism to move along the Y1 axis.

[0140] The main working steps of the motor rotor flipping and transferring device 400 are as follows:

[0141] S3a, move the clamping and flipping mechanism to receive the rotor after the rotor shaft has been hot-pressed and assembled.

[0142] S3b is used to rotate the rotor 180 degrees after the rotor shaft is pressed into the iron core.

[0143] S3c, after the rotor shaft is flipped and pressed into the iron core, the rotor is transferred to the cooling device, which is the required device for the fourth production process in the automated production line of flat wire motor rotor.

[0144] Specifically, the main features of the cooling device, the equipment required for the fourth production step in the automated production line for flat wire motor rotors, are as follows:

[0145] The cooling device is used to cool the heated annular iron core in the rotor shaft assembly device 300, and to transfer the cooled rotor to the fifth production process in the flat wire motor rotor automated production line—the rotor iron ring hot pressing device 600.

[0146] Specifically, the main features of the equipment required for the fifth production process in the automated production line of the flat wire motor rotor—the rotor iron ring hot pressing device 600—are as follows:

[0147] The rotor iron ring hot pressing device 600 is used to hot press manually fed iron rings into the rotor. After the iron rings are hot pressed into the rotor, the rotor is transferred to the laser marking device, which is the sixth production process in the automated production line of flat wire motor rotors. The main structure and working steps of the rotor iron ring hot pressing device 600 are as follows:

[0148] like Figures 36-39As shown, the rotor iron ring hot pressing device 600 includes an automatic iron ring feeding device 500, an iron ring heating mechanism 601, an iron ring rotor transport mechanism 602, and an iron ring gripping mechanism 603. The iron ring gripping mechanism 603 can move the iron ring arbitrarily among the iron ring heating mechanism 601, the iron ring rotor transport mechanism 602, or the automatic iron ring feeding device 500. The iron ring rotor transport mechanism 602 includes an iron ring rotor transport slide rail 602a, a transfer platform assembly 602b disposed on the iron ring rotor transport slide rail 602a, and an iron ring rotor transport drive assembly 602c that drives the transfer platform assembly 602b to move on the iron ring rotor transport slide rail 602a. The iron ring rotor transport drive assembly 602c can adopt a motor screw structure. The transfer platform assembly 602b is used to transfer the heated iron ring and the rotor to be hot pressed. Driven by the iron ring rotor transport drive assembly 602c, the transfer platform assembly 602b can move toward or away from the iron ring heating mechanism 601. The movement path of the transfer platform assembly 602b includes an iron ring hot pressing mechanism 604 and a rotor hot pressing transfer mechanism 605. The rotor hot pressing transfer mechanism 605 includes a rotor hot pressing manipulator 605a for gripping the rotor to be hot pressed. After gripping the rotor, the rotor hot pressing manipulator 605a can place it onto the transfer platform assembly 602b. The iron ring hot pressing mechanism 604 includes an iron ring gripping hot pressing assembly 604a for gripping the iron ring and pressing the heated iron ring into the rotor. Specifically, the iron ring hot pressing mechanism 604 is located between the rotor hot pressing and transfer mechanism 605 and the iron ring gripping mechanism 603. The iron ring hot pressing mechanism 604, the rotor hot pressing and transfer mechanism 605, and the iron ring gripping mechanism 603 are all fixed on their respective frames. The iron ring rotor transport slide rail 602a is located below the iron ring hot pressing mechanism 604, the rotor hot pressing and transfer mechanism 605, and the iron ring gripping mechanism 603. The automatic iron ring feeding device 500 and the iron ring heating mechanism 601 are located on both sides of the iron ring rotor transport slide rail 602a.

[0149] During operation of the rotor iron ring hot pressing device 600, the automatic iron ring feeding device 500 can accommodate several iron rings. Simultaneously, the iron ring gripping mechanism 603 grips an iron ring from the automatic feeding device 500 and places it on the iron ring heating mechanism 601 for heating. At the same time, the transfer platform assembly 602b moves to a position below the rotor hot pressing transfer mechanism 605. The rotor hot pressing transfer mechanism 605 receives the rotor to be hot pressed from an external device and places it on the transfer platform assembly 602b. After receiving the rotor, the transfer platform assembly 602b moves to a position closer to the iron ring heating mechanism 601. After the iron ring is heated, the iron ring gripping mechanism 603 transfers the heated iron ring to the transfer platform assembly 602b. The transfer platform assembly 602b then transfers the heated iron ring and the rotor to be hot-pressed to the iron ring hot-pressing mechanism 604. The iron ring gripping hot-pressing assembly 604a hot-presses the iron ring into the rotor. During this period, the iron ring gripping mechanism 603 continues to grip an iron ring from the automatic iron ring feeding device 500 and places it to the iron ring heating mechanism 601 for heating, preparing for the hot pressing of the next rotor's iron ring. This invention, through the setting of the iron ring gripping mechanism and the iron ring rotor transport mechanism, allows the heating of the next iron ring to be hot-pressed while the iron ring is being pressed into the rotor, effectively improving the efficiency of rotor iron ring hot-pressing assembly. It is suitable for automated production lines for flat wire motor rotors.

[0150] In this embodiment, as Figure 40 and Figure 41 As shown, the iron ring heating mechanism 601 includes an iron ring heating platform 601a, an iron ring heating coil 601b on the iron ring heating platform 601a, and a cylindrical iron ring heating fixing block 601c on the iron ring heating platform 601a. ​​When heating the iron ring, the iron ring is placed on the outside of the iron ring heating fixing block 601c, with the bottom of the iron ring contacting the iron ring heating coil 601b.

[0151] In this embodiment, as Figure 38 , Figure 42 and Figure 43As shown, the iron ring gripping and hot pressing assembly 604a includes a pressure head module 604aa and an iron ring hot pressing drive module 604ab that drives the pressure head module 604aa to move along the height direction. The pressure head module 604aa has a rotor pressure block 604aaa, and the rotor pressure block 604aaa has a receiving part. The rotor pressure block 604aaa has an opening that communicates with the receiving part. The receiving part has a heating iron ring gripper 604aab for gripping the heated iron ring, and an iron ring gripper cylinder that drives the heating iron ring gripper 604aab to extend out of the receiving part or retract into the receiving part. The heating iron ring gripper 604aab is made of magnetic material and can pick up the iron ring. The iron ring gripper cylinder drives the heating iron ring gripper 604aab to move along the height direction.

[0152] After the iron ring is heated, the iron ring rotor transport mechanism 602 transports the heated iron ring and the rotor to be hot-pressed to below the iron ring hot-pressing mechanism 604. The iron ring hot-pressing drive module 604ab drives the pressure head module 604aa to descend, and the rotor pressure block 604aaa and the heated iron ring gripper 604aab follow suit. The iron ring gripper cylinder pushes the heated iron ring gripper 604aab to extend out of the receiving part, and the heated iron ring gripper 604aab adsorbs the heated iron ring. After the heated iron ring gripper 604aab adsorbs the heated iron ring located on the iron ring rotor transport mechanism 602, the iron ring hot-pressing drive module 604ab drives the pressure head module 604aa to rise and moves the iron ring rotor transport mechanism 602. After the rotor to be heated is placed directly below the heated iron ring, the iron ring hot-pressing drive module 604ab drives the pressure head module 604aa to descend again, and the iron ring is fitted into the rotor shaft of the rotor to be hot-pressed. During the pressing process, the iron ring clamping claw cylinder drives the heated iron ring clamping claw 604aab to move upward along the height direction. The heated iron ring clamping claw 604aab retracts into the receiving part, and the rotor shaft of the rotor to be heated also enters the receiving part. After the rotor pressing block 604aaa contacts and abuts against the rotor core of the rotor to be heated, the iron ring clamping claw cylinder drives the heated iron ring clamping claw 604aab to descend, pressing the heated iron ring into the rotor to be heated.

[0153] In this embodiment, as Figure 44As shown, the transfer platform assembly 602b includes a hot-pressing rotor loading module 602ba for loading the rotor to be hot-pressed, and an iron ring loading module 602bb for loading the heating iron ring. The hot-pressing rotor loading module 602ba is provided with a rotor positioning pin 602baa and a rotor clearance hole 602bab. When the rotor hot-pressing robot 605a places the rotor to be hot-pressed onto the transfer platform assembly 602b, specifically, the rotor shaft of the rotor to be hot-pressed is inserted into the rotor clearance hole 602bab. Due to the limiting effect of the rotor positioning pin 602baa, the annular iron core of the rotor to be hot-pressed is positioned, ensuring the smooth movement of the rotor during the transfer process by the transfer platform assembly 602b. This invention ensures the smooth movement of the rotor to be hot-pressed through the setting of the rotor positioning pin and the rotor clearance hole.

[0154] like Figure 45 As shown, the iron ring gripping mechanism 603 includes an iron ring gripping component 603a, which is a four-jaw gripper. The iron ring loading module 602bb has a gripper avoidance part 602bba to facilitate the insertion of the gripper. This invention, through the setting of the gripper avoidance part, facilitates the insertion of the gripper, thereby making it easier for the iron ring gripping mechanism to place the heated iron ring onto the iron ring loading module.

[0155] like Figure 46 As shown, the iron ring gripping mechanism 603 includes an iron ring gripping slide rail 603b arranged along the Y2 axis, an iron ring gripping slider disposed on the iron ring gripping slide rail 603b, and an iron ring gripping slider driving assembly for driving the iron ring gripping slider to move along the iron ring gripping slide rail. The iron ring gripping slider 603b is provided with an iron ring gripping cylinder 603c that can extend and retract along the Z2 axis. The iron ring gripping assembly 603a is disposed on the output end of the iron ring gripping cylinder 603c. Under the action of the iron ring gripping slider driving assembly and the iron ring gripping cylinder 603c, the iron ring gripping assembly 603a can move along the Y2 axis and the Z2 axis, thereby gripping the iron ring from the automatic iron ring feeding device 500 onto the iron ring loading module 602bb and the iron ring heating platform 601a.

[0156] like Figure 40As shown, a heating and fumigation mechanism 606 is provided on one side of the iron ring heating mechanism 601, which can move towards or away from the iron ring heating mechanism 601. During the process of the iron ring gripping mechanism 603 gripping the iron ring onto the iron ring heating platform 601a, the heating and fumigation mechanism 606 moves away from the iron ring heating mechanism 601 under the action of the driving device, facilitating the placement of the iron ring on the iron ring heating platform 601a. ​​When heating of the iron ring is required, the heating and fumigation mechanism 606 moves to a position above the iron ring heating platform 601a under the action of the driving device, absorbing the smoke generated during the heating of the iron ring and discharging it through a pipe. This invention effectively removes the smoke and dust generated during the heating of the iron ring through the setting of the heating and fumigation mechanism.

[0157] The main working steps of the rotor iron ring hot pressing device 600 are as follows:

[0158] S4a, the transfer platform assembly 602b moves to below the rotor hot pressing transfer mechanism 605, the rotor hot pressing robot 605a grabs the rotor to be hot pressed and places it into the rotor clearance hole 602bab located on the transfer platform assembly 602b; the iron ring grabbing assembly 603a grabs an iron ring from the iron ring automatic feeding device 500 and places it into the iron ring heating platform 601a for heating.

[0159] S4b, the transfer platform assembly 602b moves to the side close to the iron ring heating platform 601a. ​​After the iron ring is heated, the iron ring gripping assembly 603a grips the heated iron ring and places it onto the iron ring loading module 602bb located on the transfer platform assembly 602b.

[0160] S4c, the transfer platform assembly 602b carries the rotor to be hot-pressed and the heated iron ring to below the iron ring hot-pressing mechanism 604, specifically, so that the heated iron ring is located directly below the heated iron ring clamp 604aab.

[0161] S4d, the heating iron ring gripper 604aab extends, and after adsorbing the iron ring, drives the transfer platform assembly 602b to position the iron ring directly above the rotor to be heated and pressed.

[0162] S4e drives the pressure head module 604aa to descend, inserting the iron ring into the rotor shaft of the rotor to be heated and pressed.

[0163] S4f, the transfer platform assembly 602b carries the rotor after the iron ring is hot-pressed to the area below the rotor hot-pressing transfer mechanism 605, and the rotor hot-pressing robot 605a transfers the rotor after the iron ring is hot-pressed to the next step of the production device of the flat wire motor rotor iron ring hot-pressing device of the present invention.

[0164] Specifically, the main features of the laser marking device, the equipment required for the sixth production step in the automated production line for flat wire motor rotors, are as follows:

[0165] The laser marking device is mainly used to laser mark the rotor of the flat wire motor after the iron core, rotor shaft and iron ring are assembled. After the laser marking is completed, the flat wire motor rotor can leave the automated production line of the flat wire motor rotor of the present invention.

[0166] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way.
